[issue33011] Embedded 3.6.4 distribution does not add script parent as sys.path[0]
New submission from Cong Monkey <congzhan...@gmail.com>:
Embedded 3.6.0 distribution does not insert script parent in sys.path[0], but
the normal python do it.
this make some failed, like when I try to do pip install future, it will failed
as import src.future failed, which works for normal python.
The root source maybe when python36._pth exist, python rewrite the flag and
mark as isolate mode automate, which will not update sys.path when
pymain_init_sys_path.
I use a trick which is really bad as a work around(and even when site .main the
sys.argv is not ready!), and hope upstream will fix the root source.
===begin in my usercustomize.py:
import sys
import pathlib
class DummyImportHook(object):
def __init__(self, *args):
self.is_script_path_to_sys_path_be_done = False
pass
def find_module(self, fullname, path=None):
# print(f'{DummyImportHook.__name__} trigger {sys.argv if hasattr(sys,
"argv") else ""} ')
if not self.is_script_path_to_sys_path_be_done and hasattr(sys, 'argv'):
if sys.argv[0] is not None:
# print(f'{DummyImportHook.__name__}:argv is {sys.argv}')
path_obj = pathlib.Path(sys.argv[0])
# #if path_obj.exists():
# print(f'{DummyImportHook.__name__}:I am try to add
{str(path_obj.parent)} to sys.path')
sys.path.insert(0, str(path_obj.parent))
print(f'{DummyImportHook.__name__}:current sys.path is
{sys.path}')
pass
self.is_script_path_to_sys_path_be_done = True
pass
return None
pass
print(f'{DummyImportHook.__name__}:auto script path to sys.path hook load!')
#sys.meta_path = [DummyImportHook()]
sys.meta_path.insert(0,DummyImportHook())
===end in my usercustomize.py:
===begin in my python36._pth
python36
.
# Uncomment to run site.main() automatically
import site
===end in my python36._pth
BTW, where is Embedded distribution package script in python git repo?

CDA conversion
Good evening. I am trying to write an application in Python that will allow a person to insert a CD into their computer and this python script will convert the music to mp3. NOTE: I have already google'd this, and nothing really pops out at me. I found tons of applications that does this, but I am trying to write this myself (as a little project). Does anyone know a good site that I can find some pointers on getting started? The machine that this will run on is running Linux and has Python 2.5.

WXPython - Using inline images
I have a question about WXPython and using inline images. The code that I have included into this email comes from the following URL: http://www.daniweb.com/code/snippet654.html As you can see from the code below, that this application will take an inline JPG image, and will create a local copy of the image called zzz777.jpg. Is there anyway WXPython can just use the inline image without having to create a physical copy? I know this can be done in TKinter using inline gifs, but was wondering if anyone knew of a clever way to do this in WXPython? --- CODE -- import wx import cStringIO import base64 BG_Egypt_jpg_b64='''\ /9j/4AAQSkZJRgABAQAAAQABAAD/2wBDAAYEBQYFBAYGBQYHBwYIChAKCgkJChQODwwQFxQYGBcU FhYaHSUfGhsjHBYWICwgIyYnKSopGR8tMC0oMCUoKSj/2wBDAQcHBwoIChMKChMoGhYaKCgoKCgo KCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCj/wAARCAAgACADASIA AhEBAxEB/8QAHwAAAQUBAQEBAQEAAAECAwQFBgcICQoL/8QAtRAAAgEDAwIEAwUFBAQA AAF9AQIDAAQRBRIhMUEGE1FhByJxFDKBkaEII0KxwRVS0fAkM2JyggkKFhcYGRolJicoKSo0NTY3 ODk6Q0RFRkdISUpTVFVWV1hZWmNkZWZnaGlqc3R1dnd4eXqDhIWGh4iJipKTlJWWl5iZmqKjpKWm p6ipqrKztLW2t7i5usLDxMXGx8jJytLT1NXW19jZ2uHi4+Tl5ufo6erx8vP09fb3+Pn6/8QAHwEA AwEBAQEBAQEBAQECAwQFBgcICQoL/8QAtREAAgECBAQDBAcFBAQAAQJ3AAECAxEEBSEx BhJBUQdhcRMiMoEIFEKRobHBCSMzUvAVYnLRChYkNOEl8RcYGRomJygpKjU2Nzg5OkNERUZHSElK U1RVVldYWVpjZGVmZ2hpanN0dXZ3eHl6goOEhYaHiImKkpOUlZaXmJmaoqOkpaanqKmqsrO0tba3 uLm6wsPExcbHyMnK0tPU1dbX2Nna4uPk5ebn6Onq8vP09fb3+Pn6/9oADAMBAAIRAxEAPwB2taqm lRI7pAsCxQDi0WVizqo7KzEln9+v55f/AAlsZ/5dp+f+oI//AMa9/wDPc8c8wW3f97p3v/HD9f8A P66mtaqmlRI7pAsCxQDi0WVizqo7KzEln9+v5+J9+9tDQy/+EtjP/LtPz/1BH/8AjXv/AJ7x67q0 9xo8Lxp5AlurUc2ggk2mdAeCoYAgn6g9wea2r+Inv7aK3tILpZZLm3yV0t4fl85C2X8sYG3OeeQS O/N3xzzBbd/3une/8cP1/wA/qbWab36gHjnmC27/AL3Tvf8Ajh+v+f1PHPMFt3/e6d7/AMcP1/z+ uXr2sDV1hRIb553urU86fLGoVJYz3QKAFH+e+hresafcXapJDfSiHyDxYTsvmRhCOQhDAMo9QfcH k1te3W4Fu98UW0E/kQW8xWNEQkaQ7gsFAb5vLO75ieckHtnvia9rA1dYUSG+ed7q1POnyxqFSWM9 0CgBR/nvqf8ACWxn/l2n5/6gj/8Axr3/AM9z/hLYz/y7T8/9QR//AI17/wCe58mB/9k= ''' jpg1 = base64.b64decode(BG_Egypt_jpg_b64) # save the image to a file ... # (couldn't figure out any other way to use with wx.Bitmap) tile_file = zzz777.jpg fout = open(tile_file, wb) fout.write(jpg1) fout.close() self.bmp1 = wx.Bitmap(tile_file) wx.EVT_PAINT(self, self.on_paint) - -- http://mail.python.org/mailman/listinfo/python-list

h = ph.stdout.read().strip()

You're not seeing the 'u' in the 'print filename' line as it isn't
actually part of the data. You will see it in the 'print params2'
output, though, as I believe it relies on the string object's __repr__
function, which will include the unicode specifier.

Python Threads

I have a GUI which is spawning a thread to make a large calculation (that
way the GUI does not appear to be non responsive). I am trying to attach a
progress bar to the threaded action. As the thread is calculating data, I
would like it to communicate with the other (progress) thread to update it.
On windows, when I spawn the progress bar without using threads, the
progress bar stalls this does not happen on linux. So I thought by
spawning the progress bar by using a thread, it would not stall... If
anyone can think of another technique I am all ears.

Another Dictionary Question
Hello All.
I have a question concerning searching data within dictionaries.
Lets say I have a dictionary called db.
db = {'[EMAIL PROTECTED]':'none', '[EMAIL PROTECTED]':'none', '[EMAIL
PROTECTED]':'none',
'[EMAIL PROTECTED]':'none',}
And I want to pull out all of the gmail.com addresses.. How would I do
this?
NOTE: I already have a regular expression to search for this, but I feel
that looping over a dictionary is not very efficient.
So I have:
domsrch = re.compile(r@(\S+))
listToLookFor = ['gmail.com']
db = {'[EMAIL PROTECTED]':'none', '[EMAIL PROTECTED]':'none', '[EMAIL
PROTECTED]':'none',
'[EMAIL PROTECTED]':'none',}
I wonder if there is a way to do something like
Psuedo code
for item in listToLookFor:
if domsrch.findall(db.has_key( item )):
print horray
NOTE: I know the findall is for lists, but I dont know of an efficient way
to search for this in a dictionary.
Thanks in advance.

Dictionary/Hash question
Even though I am starting to get the hang of Python, I continue to find
myself finding problems that I cannot solve.
I have never used dictionaries before and I feel that they really help
improve efficiency when trying to analyze huge amounts of data (rather than
having nested loops).
Basically what I have is 2 different files containing data. My program will
take the first line in one file and see if it exists in another file. If it
does find a match, then it will write the data to a file.
---
Right now, the code will open file1 and store all contents in a list. Then
it will do the same thing to file2. THN it will loop over list1 and
insert into a Hash table. I am trying to find out a way to make this code
more efficient. SO here is what i would rather have. when i open file1
send directly to the hash table totally bypassing the insertion of the
script.. Is this possible?
def fcompare(f1name, f2name):
import re
mailsrch = re.compile(r'[EMAIL PROTECTED],4}')
f1 = fopen(f1name)
f2 = fopen(f2name)
if not f1 or not f2:
return 0
a = f1.readlines(); f1.close()
b = f2.readlines(); f2.close()
file1List= []
print starting list 1
for c in a:
file1List.extend(mailsrch.findall(c))
print storing File1 in dictionary.
d1 = {}
for item in file1List :
d1[item] = None
print finished storing information in lists.
print starting list 2
file2List = []
for d in b:
file2List.extend(mailsrch.findall(d))
utp = open(match.txt,w)
for item in file2List :
if d1.has_key( item ) :
utp.write(item + '\n')
utp.close()
#del file1List

You are right, a list is not the right data structure in your case. But a dictionary is a mapping from keys to values, and you have no values to store. In this case one should use a set: like a list, but without ordering, and no duplicated elements. Also, it's not necesary to read all lines at once, you can process both files line by line. And since reading both files appears to be the same thing, you can make a function: def mailsfromfile(fname): result = set() with open(fname,'r') as finput: for line in finput: mails = some_regular_expression.findall(line) if mails: result.update(mails) return result mails1 = mailsfromfile(f1name) mails2 = mailsfromfile(f2name) for mail in mails1 mails2: # = set intersection, mails present on both files # write mail to output file -- Gabriel Genellina -- http://mail.python.org/mailman/listinfo/python-list -- http://mail.python.org/mailman/listinfo/python-list

On purpose becuase I want this app to run on anything.
I have 2 very good solutions to this problem (AND I WANT TO THANK 'Gabriel

(LARGE means anywhere from 2MB to 800MB)
The files that my script needs to read in and interpret can contain anywhere
from 5 million lines to 65 million lines
I have attached 2 versions of code for you to analyze.

I am having issues with performance.
Instance 1: dict_compare.py {which is attached}
Is awesome, in that I have read a file and stored it into a hash table, but
if you run it, the program decides to stall after writing all of the date.
NOTE: once you receive the statement finished comparing 2 lists. the
file has actually finished processing within 1 minute, but the script
continues to run for additional minutes (10 additional minutes actually).
I dont know why
Instance 2: dictNew.py
Runs great but it is a little slower than Instance 1 (dict_compare.py). BUT
WHEN IT FINISHES, IT STOPS THE APPLICATION no additional minutes.
NOTE: I was not yelling with the capitalization, but I am frustrated
Can anyone tell me why Intance1 takes so long to finish? I love both
methods, but I cannot understand the timeframe differences.

Oh, sorry. You need two things:
- Python 2.5
- include this line at the very beginning of your script: from __future__
import with_statement
If you're using an earlier version, you can write:
finput = open(fname,'r')
try

finally
finput.close()
(Or just omit the try/finally and rely on the garbage collector, but it's
not the recommended practice, specially when external resources are

Re: Diff between opening files in 'r' and 'r+' mode
It was a little hard to follow your logic of your sample code (writing,
reading and writing again), but
(1)The difference between r and r+.
- 'r+' opens the file for both reading and writing.
- 'r' should be used when the file will only be read.
I am not sure on how you want to store the contents of the file, but I have
provided an example below. You could do something like this:
--
fileContent = open(fname, 'r')
a = fileContent.readlines(); fileContent.close()
print a
--
(2) If you are just going to read the file, then yes I would use just the
'r' argument.

difflib qualm
I am trying to write a python script that will compare 2 files which contains names (millions of them). More specifically, I have 2 files (Files1.txt and Files2.txt). Files1.txtcontains 180 thousand names and Files2.txt contains 34 million names. I have a script which will analyze these two files and store them into 2 different lists (fileList1 and fileList2 respectivly). I have imported the diflib library and after the lists are created, matching on the following criteria for diflib - (just the names that are similar between the two files). This works perfectly for hundreds of names but is taking forever for millions of them; thus not really efficient. Does anyone have any idea on how to get this more efficient?
